0–100, higher is better. How it is calculated

Hyli is a technology company operating a next-generation proof-powered Layer 1 blockchain platform designed to enable scalable, privacy-first applications. The company positions itself as an innovative player in the blockchain space, leveraging zero-knowledge proof technology to deliver interoperability, privacy, and performance. The website presents a professional and modern digital presence with clear messaging targeting developers, enterprises, and blockchain researchers. The ecosystem includes multiple partners and backers, indicating a collaborative and growing network. Technically, the website is built on Webflow and incorporates modern JavaScript libraries such as Anime.js, Splide.js, GSAP, and Three.js, ensuring a smooth and visually engaging user experience. Hosting is provided by Gandi SAS, a reputable French hosting provider. The site is mobile-optimized, fast-loading, and accessible, with no detected cookies or tracking scripts, enhancing user privacy. From a security perspective, the site uses HTTPS and Cloudflare Turnstile captcha for spam prevention. However, explicit security headers are not detected, and there is no published security policy or incident response information. The WHOIS data is incomplete and malformed, which reduces domain trustworthiness, but the presence of detailed legal terms and company information in French supports legitimacy. Overall, Hyli's website demonstrates a strong business and technical foundation with room for improvement in security transparency and WHOIS data completeness. The risk level is moderate, with recommendations to enhance security headers, publish security policies, and improve domain registration transparency.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

6 findings rated critical or high. Fix these first.

  1. Email security

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

    • High

      No Cookie Consent Banner found

      GDPR requires explicit consent for non-essential cookies

      What to do: Implement a cookie consent banner that appears on first visit

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Hyli operates in the blockchain technology sector, focusing on zero-knowledge proof-powered Layer 1 solutions. Its competitive advantage lies in combining onchain security with offchain performance and native privacy features without sacrificing throughput. The business model centers on providing a flexible platform supporting any programming language and proof system, appealing to developers and enterprises building decentralized applications. Revenue streams likely include ecosystem partnerships, developer tools, and possibly transaction fees on the blockchain. The company targets a global audience of blockchain builders, researchers, and investors. The partnership ecosystem is robust, featuring multiple backers and collaborators, which strengthens market positioning and growth potential. Strategic observations include the emphasis on privacy, interoperability, and scalability as key differentiators in a competitive blockchain landscape.

Security posture

The website exhibits a moderate to good security posture. HTTPS is enforced, and Cloudflare Turnstile captcha is implemented to mitigate spam and automated abuse. The absence of cookies and tracking scripts reduces privacy risks. However, the lack of explicit security headers such as Content Security Policy (CSP), HTTP Strict Transport Security (HSTS), and X-Frame-Options is a gap that could expose the site to certain web-based attacks. No vulnerability disclosure or security.txt files are present, limiting transparency for security researchers. Incident response and security policy information are not published, which could hinder timely communication in case of security incidents. The malformed WHOIS data is a concern for domain legitimacy and trust. Overall, the security culture appears nascent but with foundational protections in place.

Recommendations

  1. Implement and publish a comprehensive security policy and incident response plan on the website.
  2. Add standard security headers (CSP, HSTS, X-Frame-Options) to enhance web security.
  3. Publish a vulnerability disclosure policy or security.txt file to encourage responsible reporting.
  4. Improve WHOIS data transparency by ensuring accurate and complete domain registration information.
  5. Consider adding a cookie consent mechanism if cookies or tracking technologies are introduced in the future.

Technical notes

Notes

The website is built using Webflow CMS, leveraging a modern and performant tech stack including jQuery, Anime.js for animations, Splide.js for sliders, Lenis for smooth scrolling, Three.js for 3D graphics, Perlin Noise for procedural effects, and GSAP for advanced animations. Hosting is provided by Gandi SAS, a reputable French hosting provider. The site is well-optimized for mobile devices and delivers fast loading times. SEO is supported by proper meta tags and Open Graph data. Accessibility features are present but could be further enhanced. The technical implementation reflects a mature digital infrastructure suitable for a technology startup focused on blockchain innovation. There are no detected technical debts or deprecated libraries. Opportunities exist to improve security headers and publish additional compliance documentation.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
